Abstract
The invention discloses a flexible hollow radiofrequency treatment electrode which comprises an operating handle. The operating handle is connected with a single casing which is a flexible bendable hollow casing and comprises an input port used for infusing of conductive liquid medium and a tail end communicated with a channel of the single casing and used for delivering the conductive liquid medium to the single casing form the input port. The channel for infusing liquid to tissue is arranged, temperature of interfaces of the electrode and the tissue is lowered, carbonization and vaporization of the tissue are prevented, resistance is reduced, more electromagnetic waves and heat energy are allowed to be released to the tissue, the liquid medium is taken as heat transfer media, heat conduction and heat diffusion in the tissue are improved, the melt size of the tissue can be remarkably enlarged, and the liquid can be flexibly used on the diseased issue and exerted in treatment efficiency of chemistry, biology or radiography.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments melted for tissue, particularly a kind of flexible hollow radio-frequency (RF) therapy electrode.
Background technology
Radio entity tumor and ablation of tissue (Radiofrequencyr Ablation, RFA) be the new method of minimally-invasive treatment, application is clinically more and more extensive, therapeutic electrode is the key technology in this field, and its principle is that the radio-frequency current that generator produces is released in destination organization through the electrode inserted in human body, causes the ion oscillation frictional heat in destination organization, target tissue temperature is caused to raise, make it coagulation necrosis, damage pathological tissues, thus reach therapeutic purposes.
Existing through scope use flexible electrode due to sectional area little, electrode-tissue interface electric current density and temperature too high, have impact on electric current to tissue release, its therapeutic domain is limited, and electrode limits due to shape, do not reach the needs of clinical most of case, limit its application.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of flexible hollow radio-frequency (RF) therapy electrode.
In order to solve the problems of the technologies described above, the invention discloses a kind of flexible hollow radio-frequency (RF) therapy electrode, comprise operating grip, described operating grip connects single sleeve pipe, described single sleeve pipe is flexible flexible hollow sleeve, described operating grip comprise for infusion conductive fluid medium input port be communicated with described single sleeve channel, for conductive fluid medium to be transported to the end of single sleeve pipe from input port.
In the present invention, described single inside pipe casing is provided with more than two expansible electrodes, is provided with the electrode push rod for carrying described electrode in described operating grip.
In the present invention, described single cannula end is taper, and single cannula end leaves the hole being convenient to electrode expansion.
In the present invention, the end of described expansible electrode expands into umbrella.
In the present invention, described expansible electrode is five.
In the present invention, described single sleeve pipe is that transparent material is made.
Beneficial effect: the present invention is provided with the passage of infusion liquid in tissue, both the temperature at the interface of electrode-tissue had been reduced, prevent carbonized, gasification, resistance is reduced, allow to discharge more electromagnetic waves and heat energy in tissue, and using liquid medium as heat transfer media, improve the conduction of heat between tissue and thermal diffusion, therefore, it is possible to the volume that significant augmenting tissue melts, and liquid can be used flexibly to play chemistry, biology or radiologic therapeutic efficacy to pathological tissues.
